Scheduled Power Outage - AD Preperation

The power in our office will be cut for at least 24 hours this coming Friday evening. I'm looking at the steps needed for AD in regard to my forest root domain as I've never been in this situation before.

I have a forest root domain with 3 child domains beneath it, LUX, BRU & MIL. BRU is where the power outage will occur and where the forest root servers are located. All sites are connected via VPN.

I think I need to transfer the FSMO roles using the ntdsutil utility to a 'live' domain controller, but I would like to be 110% sure before going ahead and making mistakes.

If anyone could steer me in the right direction it would be much appreciated.

you mention 3 child domains, these will pretty much handle outage for 24 hours.....each child domain holds its own set of 3 roles, with the schema master and infrastructure master being the only ones it looks at on the parent domain....

If you have a live controller in the root domain somewhere, then sure, you can transfer the roles and it will reduce the amount of errors that you see and save yourself potential issues, but the domains will still operate if you dont take this step

See how one of the leading financial services organizations uses Recorded Future as part of a holistic threat intelligence program to promote security awareness and proactively and efficiently identify threats.

Jay, does the live controller have to be in the root domain? I was under the impression that I would need to transfer the schema master and infrastructure master to one of the domain controllers in the child domain. This does not seem to be the case.
